Bug fix in 2.66 release, irc submitted.

File with packed images crashes on load.

Do-versions now is copying Images, because texture "use alpha" has been removed...
However, it then also copied packaged images, which crashes for some reason.

For now I skip packed image copy, which keeps blender work. This versioning
code needs more checking though.
